BLAST-GAS BURNER.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed December 2'7, 1906. Serial No. 349,596.

To all whom it may concern:

Be it known that l, Josnrn SIMMENDINGER, a citizen ol the German Empire;and a resident of Wenigenjena, Germany, have invented certain new anduseful Improvements in Blast-Gas Burners, of which the following is aspecification.

This invention relates to blast-gas burners and more particularly to adevice for cutting-off the gas supply at the same time when the supplyof air under pressure is cut (Err. The device is self-acting, and whenin operation it allows only such quantity of gas to pass to the burneras is required for the byliame. The cutoff valve is automatically openedby the blast of air under pressure.

In' the accompanying drawings the device is shown by way of example.

Figure 1 is a vertical section through a blast-gas burner furnished withthe cut-oft device, which is represented in the position where the fullquantity of gas is supplied to the burner, while Fig. 2 shows thecut-off device in the cutting-off position. Figs. 3 and 4 are verticaland horizontal planes at right'angles to the plane of Fig. 1.

In a chamber of the conduit (1 for the compressed air, an axle g isrevolubly mounted which projects through the partition which separatesthe said chamber from the gas-supply pipe f. The axle g is gas-tightlypacked in said partition. A wind-wing d is fixed on axle g in theair-chamber and a spring 1' is provided for keeping the axle in such aposition that the wind-wing (1 lies horizontally over the orifice of theblast-pipe a. 011 the end of axle g which is situated in the widening ofthe gas supply-pipe f an' eccentric plate h is fixed in such a mannerthat when the wind-wing d is in normal, horizontal position, theeccentric-plate h shuts off the orifice of the gas-supply pipe leavingjust enough room that the small quantity of gas can pass, which isrequired to keep the byflame alive. When the blast is turned on thewind-wing d is blown into vertical position against the action of spring'i and the eccentric plate h is brought into the position shown in Fig.2, in which the orifice of gas supply pipe f is open, so that the fullquantity of gas is supplied to the burner.

What I claim as my invention and desire to secure by Letters Patent,is:'

A self-acting cut-off device for the gas-supply in blast gas burnerscomprising in combination an axle revolubly mounted in a widening of theair-supply pipe and pro longed through a widening of the gassupply pipe,a spring for securing the axle in its position, a wind-wing fixed uponthe axle in the widening of the air-supply pipe in horizontal positionand an eccentric plate fixed upon the axle in the widening of thegas-supply pipe in vertical position for cutting-off the supply of gasto the burner, substantially as described and shown and for the purposeset forth:

In witness whereof I have hereunto set my hand in presence of twowitnesses.
